One-Way Propagation and Complete Trapping of Terahertz Radiations in All-Dielectric Systems
Source abstract
Abstract
Surface magnetoplasmons (SMPs) in the three-layer structure of semiconductor, dielectric, and photonic crystal (PhC) are theoretically investigated. The PhC portion in the structure is designed properly so that its band gap covers the one-way propagation range of SMPs. In such an all-dielectric system, robust one-way propagation is available for SMPs at terahertz frequencies, and SMP band gap also occurs due to the PhC effect. With the use of a heterostructure of dielectric layer in the all-dielectric system, two different approaches for trapping terahertz radiation are proposed and verified by numerical simulations.
